Hi, ALL
Currently kvm hypervisor have lots of features depend on linux standard apis,
like vcpupin/mempin/processpin etc. But in the real production environment,
we need an automated resource assign and/or scheduling, is there any plan to
implement it?
resource assignment requirements like:
cpu
Hi David
Where can I get your post-copy git tree?
I wish to take a look into it first before start live-snapshot design.
Thanks.
I'm working on post-copy at the moment, using Andrea's kernel code, using bits
of Yamahata's code base as well; hopefully it won't be too long until we have
Is there any other proposals to implement vm-snapshot?
See the discussion by Paolo and Andrea about post-copy migration, which adds
kernel memory management features for tracking userspace page faults.
Perhaps you can use that infrastructure to trap guest writes.

I will look into
Good suggestion, The latest patches of post-copy seems updated 2 years
ago.

Hi, Andrea
Where can I get the dev-git-branch?
I can use it to try the snapshot prototype coding.
Thanks.

Yes, this is the tricky part. To be honest, I think this is the reason no
one has
submitted patches - it's a hard task and the win isn't that great (you can
already migrate to file).
Yes, lots of places have to be considered. Though scenarios are limited, users

Here I have another proposal, based on the live-migration scheme,
add consistent memory state tracking and saving.
The idea is simple:
1.First round use live-migration to save all memory to a snapshot file.
2.intercept the action of memory-modify, save old pages to a
temporary
I think this is different in the same way that block-backup and
block-mirror are different. Huangpeng's proposal would let you make a
consistent snapshot of disks and RAM.
Right. Though the point isn't about consistency (doing the disk snapshot when
memory has converged would be
